After transferring a domain from another registrar to AWS, I can't get it verified in the Certificate Manager. I created a hosted zone, the CNAME records created by the Certificate Manager are there, I tried with the DNS tester - the records seem good. However it still says "pending validation". I tried a few times, waited a couple of days and it doesn't seem it will work.
I'm totally out of ideas, any help?
DNS validation require 2 things to be setup correctly. Record Name and Record Value
Check if you're correctly setting these in Route53. Reference Doc here: https://docs.aws.amazon.com/acm/latest/userguide/dns-validation.html
Now 2 issues which are very common
In the Record Name part confirm that you're not adding your domain name in the value. _X is the only part you have to copy-paste. If you copy _X.YourDomain then 'YourDomain' part is duplicated
Record Value ends with . (a period / dot). Don't remove that period
You can verify the settings from https://mxtoolbox.com/ it has various configurations like A record, CNAME, DNS Validation, etc.

I'm doing my best to follow GSuite's out of date instructions for routing emails to Gmail via a AWS Route 53 hosted zone (i.e. domain). Here are the outdated instructions:
I set the Values as instructed:
And I see:
Error occurred
Bad request.
(InvalidChangeBatch 400: MXRRDATANotTwoFields (MX record doesn't have 2 fields) encountered with '')
So it will not allow me to create the records.
I had this problem with the new AWS console, but it turns out the problem was me. I had not read the instructions carefully enough.
There needed to be a numeric value (not explained) before the domain name or ip address in the value input. When I added the number, this worked for me in the new console.
I was able to reproduce this exact scenario when I used the new AWS Route 53 interface.
To resolve it I selected the use the old console. link from the top.
I then pasted the values below and it worked.
1 aspmx.l.google.com.
5 alt1.aspmx.l.google.com.
5 alt2.aspmx.l.google.com.
10 alt3.aspmx.l.google.com.
10 alt4.aspmx.l.google.com.
For now use the old console for doing this would be my suggestion.
You need to enter more than one value. This is working fine
There's something wrong with the new Route 53 console. I tried the exact same things in the old console and it worked immediately.
I hope AWS fix this soon. For anyone experiencing this issue in the mean time, try simply reverting to the old console by clicking the link on the left hand panel:
So actually what MX record consists of is a priority and a host. The smaller the number the higher the priority. You can look it up on google as well.
It appears that the cause of the problem is the nature or length of the whitespace between the priority and the host on each line. Reducing all this whitespace - on each line - down to a single space resolved the matter for me.
This seem to worked for me in Route 53

I am trying to set up a few SSL certificates in Amazon Certificate Manager, but I am trouble getting them verified after adding the CNAME in Namecheap.
Here is an example of the CNAME verification entries at Amazon Certificate Manager
Here is an example of another domains CNAME entry at Namecheap
If I put the entire value of the Name entry into Host at Namecheap, the verification fails. I also get an error on some long domains I have, as the Name entry exceeds 60 characters.
Can anyone assist with the correct parts needed to verify via DNS using Namecheap?
In the CNAME record enter - _cff0cda88701846cbe7a34cd737378e2 as the host field and - _490287b8f448e2cca3862ebb4a51591.acm-validations.aws in the value field.
Once done wait for at least 1 hour for the changes to reflect.
If anyone is looking for NameCheap DNS record validation for AWS CloudFront ssl validation then please refer screenshot below. This NameCheap DNS record validation worked for me as of Jul 2019
Adding a more complete answer.
Some DNS provider like Namecheap appends the bare domain name to the DNS record. In effect, if you add the full record provided from Amazon Certificate Manager like so (replace example.com with your domain):
_cff0cda88701846cbe7a34cd737378e2.example.com
What you'll end up with is
_cff0cda88701846cbe7a34cd737378e2.example.com.example.com
To check if this is the case, after you have added the DNS record, run this command (on Unix)
dig +short _cff0cda88701846cbe7a34cd737378e2.example.com.example.com
If it returns the CNAME record, you have to omit the domain name from your DNS record so you won't get a duplicate domain name in there. Then run
dig +short _cff0cda88701846cbe7a34cd737378e2.example.com
You should get the corresponding CNAME record from it. The validation can take up to 48 hours.
Even though AWS includes it, do not include the domain name itself in the CNAME Host field for Namecheap (they apparently append it for you); just chop that off at the end. The value field is fine.
Give it half an hour.
namecheap.com does now allow a leading underscore in the Value field.
As specified in the AWS docs' Troubleshoot DNS Validation Problems ,
you can remove the underscore from the ACM-provided value and validate your domain without it.
In your case, the Value would be:
490287b8f448e2cca3862ebb4a51591.acm-validations.aws.
Where the trailing dot should still be permitted.
For any one using a subdomain like - api.example.com.
In the CNAME record enter - _cff0cdhash.api as the host field and - _490287b8f4hash.acm-validations.aws in the value field. As namecheap itself appends example.com to it. I was not able to figure out a way to make it work for www.api.example.com.
above worked for me except for the root domain validation ; there I had to add entire string _cff0cda88701846cbe7a34cd737378e2.example.com
instead of _cff0cda88701846cbe7a34cd737378e2. for the certificate to be issued.
For the others, _cff0cda88701846cbe7a34cd737378e2.www was enough. Hope it helps. Just did this today.
I have a group of micro-services hosted on AWS, these services interact with each other through request/response using DNS name defined on Route 53 at which i created a new private zone named api.io and defined the DNSs for example WSG_KAFKA, in my code i have configure the DNS name with the zone name like WSG_KAFKA.api.io
Is there is any way to ignore the domain name api.io and use the DNS name directly
To use the hostname directly you need to edit your /etc/resolv.conf and add search api.io option, so your file may look like:
search api.io
nameserver 10.0.0.2
That will help to just search your hostname by just using WSG_KAFKA.
From the man resolv.conf:
search Search list for host-name lookup.
The search list is normally determined from the local domain
name; by default, it contains only the local domain name.
This may be changed by listing the desired domain search path
following the search keyword with spaces or tabs separating
the names. Resolver queries having fewer than ndots dots
(default is 1) in them will be attempted using each component
of the search path in turn until a match is found. For
environments with multiple subdomains please read options
ndots:n below to avoid man-in-the-middle attacks and
unnecessary traffic for the root-dns-servers. Note that this
process may be slow and will generate a lot of network traffic
if the servers for the listed domains are not local, and that
queries will time out if no server is available for one of the
domains.
The search list is currently limited to six domains with a
total of 256 characters.
I configured a primary and secondary record sets in AWS Route53.
I am using an ALB (Application Load Balancer) for my primary, and a Web hosted S3 static page for my secondary. So both Record Set type is set as CNAME.
The name of the Record Sets:
Primary: route53.samplesite.net
Secondary: route53.samplesite.net
I was able to redirect my page to the secondary whenever the primary is down.
However I have one problem. My primary is consisted of several applications that works independently. When I say independently, I meant that I do the maintenance to each application separately so they are down at different times.
So, there's domain1, domain2, domain3 and so on set as my primary.
I wanted to set only one Secondary page for all my primary records and was hoping that it could work once I changed the domain name of the secondary to:
*.samplesite.net
and leave the primary to route53.samplesite.net,route53-2.samplesite.net, etc...
This is the only approached I tried but it is not working.
I know that it will work if I set a different secondary for each primary but is there any easier and a better way to accomplish my goal above?
No, there isn't.
On the right hand side, the * is not interpreted the same way it is on the left. It gets no special treatment as a target.
There is no way in Route 53 to map *.example.com to reference e.g. *.example.org so that for any value, the answer contains the same prefix with a different suffix. You'll need to configure them individually.
I am trying to upload zone file from godaddy to AWS, when I copy paste the zone file content to AWS and click upload, the following error appeared:
Error parsing zone file: Error in line 38: Invalid address: >>++PARKED1++<< (encountered after 1 correct records)
In line:
# 600 IN A >>++PARKED1++<<
It looks like your domain was 'parked' with GoDaddy at the time you tried to export you zone file. >>++PARKED1++<< is an internal variable which GoDaddy use in there DNS Db.
The actual record is an A record and you should just replace >>++PARKED1++<< with the external IP address of your hosting provider. (e.g 1.1.1.1)
After the change you should expect that line of the config file to read as;
# 600 IN A 1.1.1.1 (For example.)
The GoDaddy help page also says;
The exported data follows the BIND zone file format and RFC 1035. You
must manually edit the exported data before a BIND DNS server can use
it directly. These edits will differ based on the requirements of the
server to which you are uploading the exported file.
But sadly it does not provide any useful pointers to the reader as to what exactly needs to be changed...
If you are mapping to an elasticbeanstalk.com endpoint then you shouldn't use an IP address (as they may change) and instead change the record type to ALIAS and then add the name of your endpoint xxxx.elasticbeanstalk.com
I was stuck exactly here for a while, and I think I might have an answer.
In place of the -parked- / missing 'a record' value, use the IP of the current application with a temporary adress.
For example, the IP address of example.eu-north-1.elasticbeanstalk.com
If unknown this IP address can also be found at www.whatsmydns.net.
Just type in the temporary address (e.g. the EB url address above) and the IP will show.
I.e. this is the -A Record- to use in place of the word -Parked-... copy & paste.
A second update on this..
After a couple of days I learnt that method above did not work too well.
Essentially, the A - IPv4 address of my EB app kept changing every so often.
Instead I updated the A Record to ALIAS (by ticking Alias = Yes) then entered the address of my EB app. Example xxxxxx.elasticbeanstalk.com
So far this has worked..
Just remove that line and use import. After the import, you can add the alias to the IP address
